System。*名称空间与自定义名称空间冲突

Question

I have a problem with a custom namespace that collide with the namespace System.*

Setup

I have a custom library with the namespace Powerdoo.System it hold multiple tools and Extension of mine.

I have a Application that reference my custom tool library and includes a Entity Framework model. The namespace of the application is Powerdoo.Model.MSSQL .

Problem

My custom namespace collides with the .Net default namespace System.* .

Like here the "using System" is interpreted as "using Powerdoo.System":

Question

Why is this happening and how can I avoid this problem without rename my tool library namespace or my application namespace.

Update 1

Here is the reference tree of the application:

Update 2

If I use rigth-click > auto name space the reference using global::System.Data.Entity; is added.

How can I bring Entity Framework to use global:: usings on auto generated classes?

Answer 1

You can use "global::System" for the .net System namespace. For your case, you have to alter the EF template.
